Jon Robert "J.R." Holden (Russian: Джон Ро́берт Хо́лден; born August 10, 1976) is a retired American-Russian professional basketball player, currently serving as an NBA Director of Player Personnel for the Brooklyn Nets. Holden was born in Pittsburgh, Pennsylvania. At 1.85 m (6'1") tall, he could play at both the point guard and shooting guard positions, but he primarily played at point guard.
As a member of CSKA Moscow, Holden won two EuroLeague titles, in 2006 and 2008. Moreover, he reached eight consecutive EuroLeague Final Four tournaments, a record he shares with his former CSKA teammate, Theo Papaloukas. His consistency at the highest level of European basketball earned him a selection to the EuroLeague 2000–2010 All-Decade Team.
He was also a member of the senior men's Russian national basketball team, which he helped lead to the FIBA EuroBasket title in 2007, Russia's first ever gold medal in the tournament.
